The first stereoselective synthesis of the specific EP1 receptor agonist, 16,16‐dimethyl prostaglandin E21, is described. The key intermediate 3 was obtained from the E‐allyl alcohol 6 via Sharpless epoxidation followed by stereospecific transformations to the γ‐iodo vinyl compound 3. Two component coupling of 2 and 3, using the dilithiocyanocuprate technology, gave the 1,4‐addition product. Mild desilylation
描述了特定 EP1 受体激动剂 16,16-二甲基前列腺素 E21 的首次立体选择性合成。关键中间体 3 通过 Sharpless 环氧化从 E-烯丙醇 6 中获得,然后立体定向转化为 γ-碘乙烯基化合物 3。2 和 3 的双组分偶联,使用二硫氰基铜酸盐技术,得到 1,4-加成产物. 温和的脱甲硅烷基化和酶促酯裂解以高产率生产光学纯的前列腺素 1。
